A mobile device and a corresponding control method are provided. The mobile device includes a life sensor, a driver, a touch detector, a heartbeat detector, a controller, and a processor. The controller controls the driver to send a first driving signal. The life sensor generates a first sensing signal in response to the first driving signal. The touch detector determines whether the mobile device is touched or not according to the first sensing signal. The controller controls the driver to send a second driving signal when the touch detector determines the mobile device is touched. The life sensor generates a second sensing signal in response to the second driving signal. The heartbeat detector determines whether the second sensing signal includes a heartbeat pattern or not. The processor executes a corresponding operation according to whether the second sensing signal includes the heartbeat pattern or not.一種行動裝置與對應的控制方法。上述行動裝置包括生命感測器、驅動器、觸碰偵測器、心跳偵測器、控制器、以及處理器。控制器控制驅動器發送第一驅動訊號。生命感測器因應第一驅動訊號而產生第一感測訊號。觸碰偵測器根據第一感測訊號判斷行動裝置是否被觸碰。當觸碰偵測器判斷行動裝置被觸碰時，控制器控制驅動器發送第二驅動訊號。生命感測器因應第二驅動訊號而產生第二感測訊號。心跳偵測器判斷第二感測訊號是否包括心跳特徵。處理器根據第二感測訊號是否包括心跳特徵而執行對應操作。
